In this patch we keep track of the cached kmsmem in a way that we can clear the cache during the drain process. This release the framebuffer before waiting for the next vblank, hence add support for DRM driver (like Intel one) that release the associated DMABuf reference asynchronously. https://bugzilla.gnome.org/show_bug.cgi?id=782774
